I'd like to keep the current statement, originally I wanted to put "2 weeks as the maintainer timeout" but I think it is somehow too long. Maybe adding "if it exceeds 2 weeks as the maintainer timeout, you definitely need to ask for attention." ?
instead of adding a new phrase, I would just extend the initial phrase:
It may take minutes, or it may take one or two weeks - so please be patient. If it takes any longer, please seek for help on mailing lists (firstname.lastname@example.org), irc: #bsdports on efnet or #freebsd on libera for example.
