I'm not sure (see how all these paragraphs start with the same phrase?
I guess we need better documentation of our maintscript snippets)
whether I know all reasons for this, but one is that if a package that
provides hyphenation patterns is removed, we want the format to be
recreated without these patterns.

If that were the only reason, though, we could add that code only when
dh_installtex knows about hyphenation patterns.

Yes, but that won't have "allformats" in #WHATTODO#, but "language".
This part still uses dhit_build_format.

And that would have to use "allformats".  However, such a package would
not conform to our TeX policy:

| Packages are free to add configuration items to the common
| configuration files, but they should not try to override configuration
| items that are supplied by other packages. Rather, shared
| configuration items should be supplied by the Basic TeX packages or
| any other package on which all involved packages depend, with a
| setting appropriate for all. [...]

(I'm inclined to change that into a "must not".)

Any even more ugly solutions, anyone? ;-)
