I'm no tactician and this is my opinion but, long story short, use whatever profile gets you the best results without loss.
Like said earlier, in a high risk environment you'd likely be forced into performing a low ingress, pop up, identify a target and employ ordinance against it, roll inverted, pull back down to the deck popping flares while you do.
For lower risk environments they'll set up a hard deck with which pilots are not allowed to descend below (to prevent lawn darting primarily) effectively allowing pilots to shoot fish in a barrel. Think Desert Storm.
Regardless of what employment has been used in the past the employment that would be used now and in the future would be whatever provided the best effectiveness while providing sufficient protection of assets (both human and machine). If the enemy AD is such that you can fly unmolested at angels 5+ and pick out the fish in the barrel then by all means do so. If they are thick then you'll have to sacrifice targeting convenience for the chance to land back at home.
Trade offs, aint life full of em!
