Return old recursion limit capabilities

[lahma]

Now stack limits are even better than original before NET 8 after sprinkling some aggressive optimization requests.

Quite impressive. Free perf.

[adams85]

Wow, kudos! 🥇

If I may ask, what tool did you use to analyze the code and track down that these methods are the culprits? Or did you just know by looking at the code? :)

[lahma]

I used debugger breakpoint hitting until stack was deep enough and started to read frames which could benefit from the attribute.

So, no black magic, just looking at the code mostly. I'm even more impressed... 😮
