> It's definitely a form of federalism

No it's not. As one Conservative Politician said decades ago "Power devolved is power retained" (by the central government). That has been proved recently with EU powers that should have been automatically returned to Scotland following the Brexit shit-show were 'grabbed' by Westminster, the ignoring of the mandate the Scots Electorate gave to the SNP & SGreens to hold another Independence Referendum and the outrageous decision for to block Scottish Legislation on Gender Recognition which would bring Scotland into line with another civilised countries.

We were, however, perfidiously promised Federalism (or near to it) during the No Campaign in 2014. Needless to say that was reneged upon.
