Postscriptum: To be fair, after investigating a little more it seems that the cold start penalty with the new Firefox seems likely due to fixing a bug that meant uBlock and similar add-ons were previously unable to intercept the first few network connections that were happening right during startup.

So on the one hand fixing that bug makes sense and has some value, but on the other hand and in practice the increased startup time still feels rather quite annoying, too, given that my phone isn't the latest and fastest model.
