My first "twin split" was 1974. There was no issue of sound leakage, since my background was broadcasting. I used "studio" techniques to stop the bass. The only theatres that I installed that had leakage were those where the owner & architect refused to comply.
Moreover, thx, if you read the specs, did require no leakage and decent reverb times, right from the start. Indiana Jones, one of the loudest films ever mixed, played perfectly with no leakage into the other rooms. Stadium theatres are not necessarily bad by design, in fact there is a demonstratable evenness from front to back; more so than a normal auditorium. A normal room rarifies from front to back and the sound drops off. In a room with a smaller area in back (such as the Fox in Atlanta) the distance reduces the level, while the smaller volume compensates. i do not feel my rooms are perfect, but sound (& sight lines) was the driving force behind the original stadium cinemas.

Getting back on topic... the answer is clearly "NO!" Let's remember the #1 thing about THX: it was, and will always be, a for-profit company that carved out a niche in developing high-quality standards for operating procedures and practices concerning audio production, and for the equipment to play back that audio in a movie theatre. You had to pay for specific THX-certified equipment (from sound baffle and speaker wire to processor) to be installed in your theatre. You had to pay to have someone make sure your theatre was compliant. And then you had to pay for the right to have that screen THX-logo'd, $10,000 or so, each and every year. Just 100 screens would cost you a million dollars every year for the right to play that Deep Note before your movies. And when your profit margins are already razor thin, dropping that cost is easy to do.
THX, at least for movie theatres, is the past. I'm not saying it's right, and I'm not saying I like it. I'm just saying it is.
