Yes, maybe eventually such functions will go to the a package shared by
the codetools and the LCL.

True.

LCL can be used in closed source, codetools not. For some people this
is a big deal.

Some functions were moved to the RTL. The fpc team can cherry pick
whatever they want.
But there are some big differences: RTL uses system encoding and are
programmed with simple porting in mind, LCL and codetools use UTF8.
codetools are optimized for file searches. IDE has some
file name functions that work in a special way. 
The LCL+codetools functions do not support empty file names and
many treat double pathdelims as one.
