In many situation yes. I use myself XCLASSes but I also try to avoid 
using them unnecessary. You can avoid using *unnecessary many* XCLASSes 
by creating local used functions inside some class, which you have used 
an XCLASS. Then you must create only *one* XCLASS implementation and you 
can *avoid* creating two XCLASS implementation. Less XCLASS => less 
possible conflicts.

If you modify a function with XCLASS it is always modified, when certain 
class has been used. Using local version of function inside another 
class, it is possible to avoid conficts, if the class, which use the 
local function, has not been used in many situations but which can be 
called rather a termination file.
