You write "when" rather than "if" - is ignoring reasonable TTLs
current practice?
(Ignoring routing updates for small routes used to be common practice,

Ignoring reasonable TTLs is rude and should be unacceptable for the
hypothetical ISP's customers, so I assume this problem will get fixed
by normal commercial pressure. Red herring?
