The catalogue has been following hypothesis 1. Thus you cannot effectively
have new variants until you cannot prove the existence of the variant in a set,
irrespective of its production by TLG or its release onto the market by sellers.

Probably we should move to theory 2 at some stage. This might prevent the “is
it genuine or fake” question from popping up more frequently or, worse, exposing
sellers to more risk after June when PayPal will be hitting sellers for damages
when selling fakes and clones. In this regard, variants must be documented, they
must be shown to exist and they must have comparatives.[…]

I believe you missed two contributing practises / rules (of thumb):
1. “not a functional difference,”
2. “everybody knows that.”
Plates exist with full and hollow underside pins? Everybody knows that, not
a functional difference, no new entry and no need for pics or notes.
There are lots of different 3001? Everybody knows that, not a functional difference,
we won’t have 45 entries, we won’t document them all. There, here’s a 3001old
entry for you to put some of them, we won’t define which are to be put in 3001
and which are to be put in 3001old.
These variants do have been found in sets. So, if the cataloguing were really/scrupulously
following theory 1, they would have been added or documented. It’s the above
two rules that prevented that.
Rule 1 is a good rule of thumb to decide whether a variant deserves an entry.
It shouldn’t be applied to decide whether a note or a pic should be added.
Rule 2 is rather stupid (and totally human).
Would changing to theory 2 have included these variants?
I think it depends on whether the two above rules were applied or not.
Theory 2 only says a variant shouldn’t be added if you don’t have proof, it doesn’t
say a variant (entry or note) should be added even if you have proof, because
one can still apply the above two rules and decide not to.
Look at 4070: for a time, there were the slot/no-slot variants (well, still are
but one is marked for deletion), until it was finally decided that the slot was
unimportant, “of little or consequence to most users.” It has been discussed
ad nauseam whether it was intended or not, whether it was a bit of plastic that
should be there and fell or a bit of plastic that shouldn’t be there. This isn’t
important now, what is is that a line has been drawn because a line has to be
drawn.
That same “of little or no consequence” rule, the same “it’s just a moulding
artefact” remark, can be used with theory 2.
Another example:
Everybody knows the moulding can cause bubbles in (trans) 4L bars.
Everybody knows the moulding can cause lines on 4L bars.
But bubbles deserve a note (because there were many questions about it on the
forum?).
Moulding lines apparently don’t (but there were questions about their proving
fakeness on the forum).
Would using theory 2 change that? I don’t think so.
Some variants don’t have a logo, or ©, or ID. Does that deserve an entry? A
note?
Applying theory 2 doesn’t change that.
What we need is to decide what is important and what is not, and to document
that.
A “what everybody should know” page? But who would read that?
Or a note on each every and every part (“can have bubbles” “may not have a logo”…)?
No more unwritten rules. No more rules of thumb. No more whims.
That won’t prevent discussions or the need for case by case decisions but it
would be clearer and more consistent.
