    The problem is that I've never noticed any positive effect of stealth
    fontification, whereas any setting, no matter how low will eat up my battery
    for no good reason.

Aside from the peculiar AUCTeX issue, does anyone see a benefit in
stealth fontification?  Is the idea that it avoids delays when you move
to other parts of the buffer, because they've been fontified while
you were on the phone?
