Oops, sorry, I confused libraries and packages.
I assume auxiliary files are per packages, so
what's required is that "everything in package
expands inside one directory specific to the package".
So sub-libraries in a package don't need implicit file.

I don't see it so much problem, better than having ^main^,
but opinions vary...

Ah I see; "in 'foo'" means "directly under 'foo', not in
a subdirectory of 'foo'".  English is difficult.

After all, I feel that my opinions are not very strong.
So my position is:

- A package untars into single package directory may be desired.
  -- this means some sort of implicit filename is required.
- ^main^ looks just a little bit too ugly to me.  but I don't
  have alternatives that are technically better.
