I agree with Scott. I can still get a /28 on a consumer DSL line for
$25/mo and routers renumber easily. There is no burden here.

I would entertain up to 5, allowing a comfortable fit in a /29 before
requesting ARIN space. Beyond that the logistical problems become
noticeable enough to merit a direct assignment. Not so severe as to
require it, but noticeable.

I would agree to a /26 minimum assignment for IXPs, but I note that
doing so complicates the critical infrastructure policy. There are
other critical infrastructure uses for which the ISP-enforced /24
boundary is an issue.
