Re: omitting collection-fontsextra installation by default? (RFC)

I was bitten by this.
archlinux used to omit collection-fontsextra, and it actually worked pretty well, except for certain packages.
For me, it was mathrsfs, which was missing the rsfs font.
I got it working with

tlmgr --usermode install rsfs

but I wouldn't have had to do that if rsfs was already a part of collection-latexrecommended.
It seems perfectly fair to me that rsfs should be a part of latexrecommended.
Either that or mathrsfs should *not* be in latexrecommended.

As a workaround, archlinux had to include (ALL OF) fontsextra to resolve this, and probably other missing dependencies, because there are probably many other examples of this.

What I suggest is to just add only the fonts that a collection needs to that collection.
So, rsfs would get added to collection-latexrecommended.

All of the fonts don't need to be added all at once.
This work can be done incrementally, starting with the most common fonts, like rsfs.

The only potential problem I see is some kind of conflict if a package is in two collections.
But that shouldn't be a problem.
Right?
I hope...
