You could get more creative with with what test you limit also. For example
to limit to all "a" libs you could do "--limit-tests=a". Or multiple ranges
like "--limit-tests=[a-c]". The arg is a simple regex so you might be able
to get clever enough to make it short.

I'll add it in because..

That is rather hard to achieve. And I'd have to think about how to do that.
As it would require some core b2 changes to pull off.

Maybe another choice would be to modify the dependency tool to spit out a
set of options to use. I.e. you might run it like this:
b2 `boost-dep --limit-tests=my-lib`
And it would return the list of options for all the dependent libraries.
