Comment (by snc@…):

 Replying to [comment:14 mojca@…]:
 > I would also suggest to add/check the SHA sum of the commit (even when
 dealing with tags) just to be on the safe side.

 Using commitish over tags is helpful and uniform.

 > Once that gets implemented – how would you handle GitHub and BitBucket
 from that point on? And how would you handle situations when the servers
 go offline? Would you mirror the bare repository on one of MacPorts
 servers? (This is of course less important.)

 There's no need to mirror their repositories. The authors can easily host
 it elsewhere and we simply update the portfile.
