As Jürgen said,

:help c_<Esc>

explicitly explains that <Esc> behaves like <CR> in maps or macros, or
when 'cpoptions' contains 'x'. I'm sure the reason for this is that
there's a pretty good bet that if a map does ":w<Esc>" it's a
vi-compatible macro that wants to write the file, meaning that
changing this behavior would break even the most simple vi maps that
users might have wanted to bring forwards, even though it's unlikely
that the user really wanted to do some work and then throw it all
away.
