That is the general idea yes, but the non fp versions have already mostly
been removed in 2.6.0 and +.

The "text" versions however were never updated because IMHO they were ill
defined, and bugreports about them lingered forever.

So I deprecated them pending a review. Maybe it is wise to remove them in
2.8.0 if by then nothing has happened. I made a note about it.
