s/getmail/getmail6 before freeze (package superseding)

["Jean-Yves Migeon (NetBSD)" <jym%helkyn.org@localhost>]

Greetings everyone,

Freeze approaching, I would like to migrate our current mail/getmail to 
-6 fork, as this version supports python 3.

With latest upstreamed fixes getmail6 can replace 1:1 getmail5.

State wouls be:
- mail/getmail is under 5.17, supports only python 2;
- mail/getmail6 will be updated to 6.19.10 (latest), supports python 3.

ATM I know there are users that use both available versions (my case 
until recently). What is the recommended path forward?

1 - update mail/getmail to 6.19.10, remove mail/getmail6 pkg, mark 
mail/getmail as SUPERSEDES of mail/getmail6;

2 - remove mail/getmail, and mark mail/getmail6 as SUPERSEDES of 
mail/getmail?

3 - (1) + have a mail/getmail5 pkg around as "best effort"?

4 - Other options (suggestions)

Considering the latest fix I had to upstream to get getmail6 to work, I 
can assert that the bugs are present in getmail5, and very unlikely to 
be fixed considering the divergence between -5 and -6. YMMV if you keep 
using it with python 2 (likelihood: pthread cv deadlocks).

FWIW I contacted schmonz@ (getmail5 maintainer), but had no feedback yet.

CC'ing all listed maintainers.

Cheers,
