Subject: MAPP gas vs. Acetylene

Why hasn't acetylene been replaced by MAPP gas for general purpose use?

Isn't is safer, no bulky tanks filled with acetone, no drawdown
limit, etc?

I'm no expert, but when I was looking at propane vs. acetylene I was told by
a supplier that the only gas that welds worth spit is acetylene.

Too True.  One safety measure you can take, however, is to use 
Acetylene regulators instead of the cheaper Propane regulators.  
Propane regulators vent externally.  Acetylene regulators do not.  
Important to know, depending on where/how you work.
