Luke Dash Jr has been wanting this for half a decade.  And it gets rehashed each time some bogus use of the scarce block space happens where things other than bitcoin transactions end up being included (such as the Veriblock transactions in 2018/2019).

Here's one approach:

> Implemented code to allow artificially increasing your own transaction weight, so that miners who include it can't make blocks quite as big. This requires NO FORK - it CAN be used today (but see CAVEATS below... Use at your own risk!).

Now as far as this being a "serious take"?   Not really, but it is not something being dismissed entirely either:

Reducing the block size? Is this a serious take?
