[...] What might be reasonable is a small facility to search for a
package that provides a virtual feature, in this case 'mua. Then the
default mailer would be '(lambda () (interactive) (find-virtual-feature
'mua)).
... which will be evaluated once, on startup when the executable is dumped,
at which point the packages available have nothing to do with what might be
available at runtime, which is the problem I was trying to solve with the
package-presence-default-tweaks variable.
