I don't think that's a great thing to cite, that talk prompted a series of others with (AFAIK*) the most recent being from Bart at LPC this year: https://lpc.events/event/17/contributions/16f The TL;DR is that it's not actually problem caused by devres. * I think Wolfram also talked about it at an automotive conference, but that seemed like a bit of a pitch for funding from the safety conscious
