Two remarks:

* I suggest a minor change by putting the slash to the URL base part:

     \newcommand{\doiurl}{https://doi.org/}

   Then, the complete URL cleanly consists of the base macro and
   the doi identifier:

     \href{\doiurl#1}

   And the comment in the change log becomes:

     %%     https://doi.org/ URL but may be set to old http://dx.doi.org/

* A bug fix, the code uses the *global* scratch register \toks1
   instead of the *local* \toks2; the fix:

     \edef\x{\toks2={\noexpand\href{\doiurl/#1}}}%
     \x
     \edef\x{\endgroup\doitext\the\toks2 \the\toks0}%
     \x

Best regards
   Heiko
