But this would mean that users *are* reporting. We should be happy
if this is the case. ;-)
I don't think that aliases occur often, for two reasons:
1. Recent data entries in LensFun rely on exiv2 or ExifTool names,
and at least for my lenses, these names are the same. I suspect
this is not coincidental, and that the problem largely exists
only for old LensFun data. Berlios is down ATM, but I recall
that the official LensFun tutorial recommends to "optimise" the
lens name. And hell knows where the lens names for the ol'
ptlens database came from ...
2. I think it is safe to claim that almost all LensFun queries are
against exiv2 names today. So put an exiv2 alias where necessary
and we are safe. (I personally even think that the exiv2 name
should be the canonical, and everything else an "alias".)

I think so. No code changes necessary on the LensFun side,
reliable, manageable.

As a personal comment I cite two proverbs from the Python community:
* Explicit is better than implicit.
* Errors should never pass silently.
Tschö,
