Comment (by bradlaue):

 Is there an official policy against supporting experimental XEP's in
 libpurple?

 Also, OTR shouldn't be considered an issue. OTR makes deep assumptions
 about how it's going to be used and only weakly supports multiple client
 connections. If one is using OTR one has to expect problems when multiple
 clients are connected - if anything, OTR could toggle off carbons or
 something.

 In any case I don't think that's a valid reason not to include this.
 XEP-0280 and XEP-0198 are essential.
