It would increase the build dependencies, assuming a package
maintainer wants to enable as many features as possible, but it would
*not* increase the 'package requires' footprint, merely the 'package
suggests' footprint (as Debian calls it), and it's up to the user
whether they install suggested extra packages, no?
