This is quite common to tie an underlying service announcement to BGP announcements in an Anycast or similar environment.
Yes, that is a commonly seen mistake with anycast.
I would say more like Application availability caused the BGP routes to be withdrawn.
Considering a failure mode that routes are not withdrawn even if application dies or routes are withdrawn even if application is alive, active withdrawal of routes is unnecessary complication with no improvement of redundancy. DNS (and other protocol's) redundancy is to have multiple unicast/anycast name server addresses. Just rely on it. Masataka Ohta
