According to http://meta.wikimedia.org/wiki/Help:Formula, and to my tests with texvc (debian squeeze mediawiki-math 1.15.1) these commands are not available, it would be nice if they were.
Why would someone need this for math formulas? Remeber, it's not a generic TeX parser and doesn't need to be.
For mathsf I don't know, I just proposed it for completness since it is the only other math font command. mathtt would definitely be useful when talking about a program that does math, to be able to mix math and code. For example something like: <math> \frac{a}{b} \LongRigtharrow \mathtt{dofrac(a,b)}</math> and things like that.
I added \textsf and \mathtt in r68386, \texttt and \mathsf were already present.
