I understand very well your position and I agree in the most part
with it.
But researching other things, I discovered that the code which
POSITION can use is already (in a big proportion) in the code-base
and I suggested that this can be used to implement, with ease, the
new function. If it needed to implement from scratch, or is a big
effort to do it, I agree, for sure, with you. But we must consider
some things about UDFs:

1. Are great way to extend with ease your server
2. Are not cross-platform
3. (At least for STRPOS) aren't officialy supported by Firebird
foundation.
4. Performance penality
5. Some limitations in some constructs (arguments mainly)
