Not really. 

Extension authors just have to take care to keep their output compatible. 

You can do command line parsing just like with git, but additionally you can 
change the workings of the basic commands, but then you have to take care to 
keep the output compatible. 

For example when I wrote the group extension, I made sure that the log only 
gives grouped output, when it is explicitely asked to do so, either via 
--group or via the grouped_log=True setting in .hgrc.

How many Python people decided to write an extension for hg, because it can 
very nicely be accessed via Python? 

(and which one of these has the higher effect? :) )
