When I sent my previous email I forgot one thing Nick might have meant.
Say you want to doctest just the docs for one sequence. If it is in
its own file, then it will take only 2 seconds say (instead of 10.5,
then 20, then 30...).

I think yours and Nick's work on Sloane sequences in SAGE is extremely valuable
for SAGE even if you never get more than 1% coverage. It motivates development
of other code that is needed to compute the sequences, which is good for helping
the development of SAGE.
Is there any way to see which sequences in OEIS are the most "popular", i.e.,
are the top results for queries?

It makes sense to build the implementations around themes.

Yes.
Someone clever could even make
sloane.A949832 (something where nothing has been implemented)
dynamically generates an object that looks up online or in a local database
the description and some terms. This would be done by overloading __getattr__,
I think.
