LaTeX2e can't disable this commands as it (like \small or
\normalsize) never defined them. 

The definitions are in the classes and they are not always
identical. E.g.

memoir: \@memoldfonterr {\rm }{\textrm }{\rmfamily }
KOMA: \scr at DeclareOldFontCommand{\rm}{\normalfont\rmfamily}{\mathrm}
article: \DeclareOldFontCommand{\rm}{\normalfont\rmfamily}{\mathrm}
