I like this idea! We were recently lamenting the fact that TH can't
generate haddocks. We could probably have some sort of half decent
generated docs (maybe even describing why the lens is polymorphic in the
fashion that it is!)
It also ensures that the code generator doesn't unexpectedly change its
behavior and output something with an incompatible type (not something we
anticipate happening, but could happen).

In the following code snippet it would be convenient to generate lenses
without explicit type signatures for the purpose of documentation:data A = A { _a ∷ Int, _b ∷ Int }
makeLensesNoTypeSignatures ''ASo we can have nice haddocks:
-- | Lens 'a'a ∷ Lens A A Int Int
-- | Lens 'b'b ∷ Lens A A Int Int—

I recall you (or someone else) asking for this on the Haskell channel, but I forgot to make an issue.
I definitely have no problem with adding this.
It is a clean solution to a messy problem.

Yes, it was me on #haskell
Thanks, guys.

With 3.0.2, you should now be able to do:
makeLensesWith (lensRules % generateSignatures .~ False) ''A
