I seem to remember it's related to RPKI ROV (every time the RPKI server
sends new data the BGP implementation asks for a refresh to re-validate
the incoming feed).

Or at least there is something in the back of my head that says "I have
heard someone talk about this unintended side-effect of RPKI ROV, together
with a BGP setup without 'soft in always'".

Might there be a correlation in your environment?
