I think that, for political reasons, it's unlikely that the francophone targeting measures will be diluted in the near future.
Basically a CLB 7 gives you 3 points per ability (oral expression writing expression, listening comprehension, and reading comprehension), and the 30 bonus points - so a total of 42 points. Do note that dropping below in any one or more skills will lose you the bonus points.
I got 7 and above for everything except speaking with very low intensity French lessons over 1.5 years (average maybe an hour a week, got to level A2 which is CLB 5 I think) followed by a few weeks of intensive brushing up (largely binge watching French shows on Netflix

) In my view the writing is actually pretty easy (you can get away just knowing two tenses and a decent vocabulary), the reading and listening are also doable with practice and English gives you a bit of a head start. The speaking really needs practice though.
The above is based in the TEF, no idea about the new option, TCF.
