You're right, the "correct" way would be to make an md5 or sha1 of the
file contents (not the filename) and add that to the thumbname.

I'd like that, but the most prevalent opinion has been that people
wants to have the filename directly visible in the thumbname, so
that's what I've finally implemented.

Comments would perhaps be better; adding more and more information to
the thumbnames makes them unwieldy. In fact, I've used a sxhash and
not md5 to make thumbnames more unique because they are already quite
large (as they include a slightly mangled full path).
