Some might, but most (at least in the parts of math I = read) wouldn't. The
general rule of thumb seems to be: if they look = different, they are
(mathematically) different. In my experience, more = mathematicians would
think it wrong to try and claim \epsilon and = \varepsilon did mean the same,
and I know some journal editors that would change = it.  Note that \in is
merely a stylized \epsilon, but is mathematically = distinct from all the
other "epsilon" variants nowadays. (Before = the standardization of the \in
symbol, \epsilon was used to mean "is an element = of" -- and sometimes to
also be the classical analysis "epsilon" in = the same formula!)
