Hi,

I would prefer it if packages would use DefaultSignatures conditionally, instead of creating new packages just to define a generic variant of a function. In general, though, I think it's good practice to define the defaults as separate functions (like `genericSize`) and export them, so that those not using DefaultSignatures can still write an instance easily.

Do you propose exposing genericSize conditionally?

No; it should be exported in both cases (it doesn't harm exporting it even when DefaultSignatures is supported). Cheers, Pedro
