Couldn't we deprecate more? For example this works fine. 

sage: CFF
QQ as continued fractions
sage: CFF.cardinality()
+Infinity

I would at least change the import for a lazy_import with deprecation in all.py.

Replying to vdelecroix:

That doesn't work because of #19628. The current branch gives a deprecation warning whenever an element of CFF is constructed. I think this is sufficient: you cannot really do anything useful with CFF without creating elements.

Agreed. I just want to avoid people complaining about deletion because it was not deprecated...

And regardless of this ticket, it's already documented as deprecated.
