I could understand how that might be relevant if we were discussing a character borrowed from another script but with different casing behaviour in the original script. (E.g., the character is caseless in the original script, or it is case but only the lowercase was borrowed and a novel uppercase character was created in the receptor script. This was a valid consideration in the encoding of Lisu, for instance.) I don’t really see how that impacts the discussion in this particular case.

Again, I don’t see how that impacts this particular case.

And again, I don’t see how this impacts the particular case under discussion.

Perhaps in general it cannot serve as a precedent for all things. But as noted, I think several of the things you noted have no particular bearing in this case. For the specific issue of borrowing a character from another script in a historic orthography, I think it’s a perfectly valid precedent. It boils down to this: just as there aren’t technical or usability reasons that make it problematic to represent IPA text using two Greek characters in an otherwise-Latin system, so also there are no technical or usability reasons I’m aware of why it is problematic to represent this historic Janalif orthography using two Cyrillic characters.
Btw, I suspect that calling these Latin characters is completely revisionist: if we could ask anyone that taught or used this orthography in 1930 about these characters, I suspect they would say that they are Cyrillic characters.

Clearly you’re trying to have a discussion about general principles, not about the specific characters. At the moment, I’m prepared to discuss general principles to the extent that they impinge on the particular case at hand. Other’s may wish to engage on a broader discussion of general principles (though, hopefully under a different subject).

These are not unreasonable requests. I don’t see any inconsistency in practice as it relates to this particular case, however.

I think one principle is that we do not always have to maintain a principle of orthographic script purity. In particular, in the case of historic orthographies no longer in active use that borrowed characters from another script in the LGC family, if there are no technical or usability reasons that make it problematic to represent those text elements using existing characters from the source script, then it is not necessary to encode equivalents in the receptor script so that we can say that the historic orthography is a pure-Latin / pure-Greek / pure-Cyrillic orthography (which, in terms of social history rather than character encoding, would likely be a revisionist perspective).

I'm not sure I fully understand the question so won't venture a comment.
