Recently, re.match acquired the alias re.prefixmatch (see this topic). That topic originally proposed to deprecate the original, which you don’t, but even when softened to two equivalent names forever, evidence was required that the original name caused confusion and was named differently in other ecosystems.
I expect the same burden of proof to be required here, so I’d advise you to strengthen your case by providing some pointers to why append/popright names are more right (pun intended).
