Actually the answer is to make the gravel deep. 2-4". That takes time to
become clogged with mud. When it does, you scrape it out and lay another
2-4". The depth is enough to wash seeds etc down to the base where they
don't get enugh light to germinate.

Trouble with that is you wouldn't be able to walk on it. More that about
1" of compacted gravel is like walking on a shale beach.

The type of gravel greatly affects this. Some hardly moves, rounded gravel,
like beach gravel will.

well after about 4 weeks of car traffic our 20mm hard edged shingle is
packing down nicely. The 2" deep bits are rook solid, but the 6" bits
are still a bit mushy.

But cars aren't getting bogged in it any more.
