Currently FP extensions are still widely supported by the majority of hosts, but this will not be the case for very long, as more and more hosts upgrade their systems.
I would recommend finding an alternative to FP, and getting away from relying on FPSE. Basically the time has come to move forward in technology, at least in this aspect, and those who cannot or choose not to move with it, will be stuck looking for an alternative anyway. As such, it's probably wise to get used to using something else now.
