According to Re: CPAN module giveaway there is some form of support for this now with the "The Lancaster Consensus" https://github.com/Perl-Toolchain-Gang/toolchain-site/blob/master/lancaster-consensus.md#flagging-abandoned-modules-and-modules-requesting-help

Its not clear if email stops being forwarded like the ABANDON MINOS option idea , but at least they're thinking about the problem :)

• ADOPTME as primary: this generally indicates a deceased author. Volunteers can request a takeover via modules@perl.org.

• ADOPTME as comaint: this indicates a verified, non-responsive author. The community may propose that a package be so marked following the same rules as for a take-over (i.e. multiple attempts to contact the author and a request via modules@perl.org). Volunteers can request a takeover of an ADOPTME module via modules@perl.org without an additional waiting period.

• HANDOFF as comaint: this indicates that an author wishes to permanently give up the primary maintainer role to someone else

• NEEDHELP as comaint: this indicates that an author seeks people to help maintain the module, but plans to continue as primary maintainer

With the exception of a 'takeover' from ADOPTME (which must go through modules@perl.org), CPAN authors must manage these comaint privileges using the regular PAUSE interface.

An author may also voluntarily transfer primary or co-maint to ADOPTME to indicate that PAUSE admins may transfer permissions immediately to anyone who requests it.
