Either through breaking interleaving, through excessive buffering or by delaying highly CPU intensive initialization until the middle of playback.

You may notice that I mentioned 3 variants you can decide between.
Your suggestion just replaces my point 2 "excessive buffering"
by my point 3 "delaying highly CPU intensive initialization until the
middle of playback".
I cannot see any of these to be generally more desirable than
the other, it depends on the use-case.
