Hi,
Today, I analysed the mediawiki specific tex markup in the english wikipedia.
(see
http://www.formulasearchengine.com/mediawiki%20specific%20texvc%20markup)
As expected, many of the commands defined by texvc are rarely used.
30% of the user defined commands contribute to more than 99% of the
overall use user defined commands.
I propose to deprecate those unused commands in the future, and to
introduce a process how new commands can be added in the future.
Best
Moritz
