I created two pea gravel patio areas last summer. One was close to the house and I prepared the area by digging up any grass and weeds, scraping down a few inches, and laying landscape fabric. The other area is on the edge of my pasture, and I did nothing to prepare it, other than mow the existing grass as short as possible. In both areas I laid a base of stone dust and gravel mix; I use stone dust in my paddocks and it's pretty amazing how well it can suppress weeds once it's packed down. I spread it so there was about a 2-inch base over the membrane and 3 inches over the pasture area. Over the mix, I spread about a 2-inch base of pea stone over the membrane area and about 3 inches over the pasture area. It will be interesting to see the differences as they age. The area in the pasture had a definite dip in the middle of it, so it's obviously thicker there, but I noticed along the edges where the stone is thin the grass started growing through it within weeks.

Terram1000 is the go-to for landscaping and is laid beneath most pathways - Its essentially a heavy duty permeable geotextile.
The grids (EcoGrid, Golpla etc.) are excellent for creating a sturdy, level gravel path and hold up well if you aren't able to lay a deep sub base. They also prevent gravel from being kicked, scraped or washed away which will save you time topping up later.
Resin bound gravel is permeable but needs a well compacted sub base - Typically this would be an open course macadam layer but increasingly its being laid on compacted type01 (to 150mm) with an interlocking gravel grid system on top.
Mine hasn't sunk. Maybe it depends on your soil and how wet your area is.
Nor mine - although the ground was solid from having gravel and membrane on it for years, it gets pretty wet in winter. The gravel is handy for putting in the bottom of pots too. 😁
I think that's what's happened at the Old Course in St. Andrews ...
I don't watch much TV, but i take it that was a plot line? The St. Andrews patio is a disgrace. I'm glad it is being replaced. What were they thinking of?
Re the St. Andrews' 18th hole -no idea @Balgay.Hill, but they seemed to think it would prevent the amount of [inevitable] wear and tear. I thought Ken Brown's comment was hilarious - https://www.bbc.co.uk/news/uk-scotland-edinburgh-east-fife-64538420 although the full comment isn't in that link. Barbecues were mentioned....
It was indeed a well documented plot in 'Broochheee' - wife buried under patio. Can't remember everything about it though.
It's a place where beautiful isn't enough of a word....
I live in west central Scotland - not where that photo is...
