It seems that the env var DEBEMAIL is now accepting a new syntax (at
least I was not aware of this syntax):

https://manpages.debian.org/unstable/devscripts/dch.1.en.html

[...]If the environment variable DEBEMAIL is set, this will be used
for the email address. If this variable has the form "name <email>",
then the maintainer name will also be taken from here[...]

I'll send a v2 that check DEBEMAIL does not contains '<>'.
