 I had to. Some packages use that plugin, but package maintainers were
a bit lazy to add this build dependency. Please note, of course it is
needed as a runtime dependency as well if the package uses it during
operation.
Modularization is done due to those numbers and those pulling in a lot
of dependent packages. See the original bug reports [1][2] for
example. It would have been better if maintainers add this build
dependency themselves, keeping a default graphviz installation small.
Then some of them are a bit lazy and at least in the short term it was
better to add it to graphviz itself as a default dependency.

 I would say the general answer. If your package needs a build
dependency, please consider adding that directly even if it's being
pulled in by another build dependency. That transitional dependency
might change, making your source package FTBFS.
