I would like to see some data on how many of these petitions that garner enough support actually end up changing anything for the better.

Government responded: “It’s ‘Winner takes all’, not ‘Winner takes most things’ “

The government has no plans to "good thing"

Please don't stop signing petitions though. It takes little effort and forces them to justify their unpopular policies in Parliament (admittedly usually to a very empty chamber).

Government responded:

we talked about this 9 months ago clearly we dont need to talk about it ever again
