It’s worth pointing out:
1) Prorogation is what happens – every single time – before a new session of Parliament with a new Queen’s speech can take place.
2) The current Parliamentary session is the longest since the Rump Parliament was dissolved in 1653, which had similarly out-stayed its welcome. It’s been over 2 years since the last Queen’s speech and anything like a legislative programme existed. If we’re looking to constitutional “outrages”, one can begin there.
3) Anything we are proceeding towards in the meantime – such as an exit from the EU on WTO terms in the absence of any alternative treaties – will happen only because of legislation voted for by the current crop of MPs. They legislated that into law.
4) Of course, the reason certain MPs are protesting this (in rather overblown terms) is because of the desire they have to undo the laws they’d already agreed to and effectively void the largest vote in British history. Their proposed “government of national unity” would be a real outrage, since it wouldn’t represent national unity, only parliamentary unity against said vote and the nation.
