Well, it's an issue of time. Just building and adding the deps is fast
and straightforward. A tool I'd need to know about, have installed,
and remember to use in the middle of a Cabalizing session. The people
who most need such a tool are those who are least likely to use it.
And given the overhead, it's unclear that it would actually save time.
Sometimes, somethings aren't worth automating.

Now, if someone were to create such a tool and integrate it into
'mkcabal', then it might make sense. You could create the basic .cabal
with the build-depends filled in. But as a separate tool it's too
small a task to handle. Even memorizing the -show-iface or
- -ddump-types options may not be worthwhile - how often does one create
Cabal packages from scratch?
