I'm uncertain whether fgl conforms to the package versioning policy, but if it does, then changes in its Cabal file should not bother sifflet. Thus upper bound fgl < 5.4.3 should be restrictive enough.

The PVP says that one of the first two numbers are required to change if an API change is likely to break code using it, so < 5.5 would probably suffice.

A bump to fgl-5.4.3 might include API *extensions* that may break sifflet, if it imports entire FGL modules in an unqualified way.
