Have to stick with Kae'Yoss on this one. B-S-T was never an issue IMC, IIRC. I can't remember a session when the players diskussed that tactic in detail to attack a major villain...Reasons:
First, the foes at high/epic levels very often use Mind Blank (a spell I don't really like as a DM, but what's good for the goose...).
Then they sometimes use a Forbiddance. Or a Weird Stone, a nice teleport blocker (see PGtF).
Third, even if the party is able to do the B-S-T thing, the PCs rarely know details about the foe's defenses. That includes monsters, traps and ongoing spells, like a greater glyph combined with a greater dispelling...
If a party would try a B-S-T while I am DM, and there would be a bad preparation, i.e. not gaining more knowledge about the destination area, I wouldn't hesitate to pull out all stops to make the BBEG worth his salt. And that could include a TPK, no mercy...
The players I know used more often the combo Wind Walk, Invisibility and Telepathic Bond. If there are no good counter measures, a party may strike at important positions without draining its powers in fighting mooks or getting around traps before.
