# [texhax] Why is \rm deprecated?

The fact that it is is clear.  I would like to know why it is deprecated.  I continue to use it because it is familiar and reduces the number of new things I have to use.  It works well, and in both text and math and, as was clear from my original question, in some situations it works better than the alternatives.  There must be some substantive reason it is deprecated.

In a similar vein, why is it recommended to use $$...$$ for equations and $...$ for displays?  I have defined a single function that lays down a pair of \$ and leaves the cursor between them.  Hit it twice and I am in display mode.  Meanwhile I use \( to as a macro for \left( and similarly for the others.  TeX is tool, not a religion.  Why are people trying to enforce conformity?  Foolish hobgoblins.
