As long as you don't mind these being added after the fact, I suppose
it would be workable.  The reason I say that is sometimes, it even catches *us*
by surprise.  We recently found out our virtualisation guys started
using sch_htb for example, and we inadvertantly broke it when we moved
its module to a 'not always installed' kernel subpackage. (and before that, 9PFS..)

People don't tell us anything, but somehow expect things to keep working.

I wish defconfig was actually something useful like this, instead of..
what the hell is it exactly ? No-one even seems to agree, other than
"random selection of options, many of which were removed n years ago"
