Yes, quite often.

And the content this thread started around is normal, which is mostly dungeons. While the dungeon bosses themselves easily allow ABCing, the meta of big pulls does not. A lot of your ability to deal damage in those settings rests on the shoulders of others. In that regard, healing is very reactive, and an instant cast at the wrong time that locks up your GCD suddenly means many of your OGCDs may be required to adjust, and that leaves you more vulnerable moving forward. Not in small pulls, not on most normal bosses, but wall-to-wall pulls, it's much less cut and dry than its being presented.
