The first time I needed a permalink to particular tweet, I spent good five minutes looking around for it. Only accidentally I noticed that the timestamp has it, and it didn't strike me as obvious at all.
Having a link which clearly says 'Details' seems much more intuitive in this case. And even if it was indeed Twitter who has started this pattern of linkifying timestamps, now it could be considered as them backing off from confusing UX decision that many sites parroted.
