No idea, I do this quite regularly:

And the one thing that I've noticed is that my hip function improves for the next few hours, but the next time I do this mobilisation, my ROM is back to where it was before.
Sounds like you're getting the test/re-test result. Static stretching of joint capsules, supporting musculature is horridly painful to achieve full time ROM improvements, and needs to be done regularly to improve long-term.
For example, to improve my adductor situation, I static stretch 2/3 times a week and then dynamic stretch 3-5 times a week to make sure the ROM is still there prior to warm-up.
I'm not scared to static stretching before a workout, either, and if I know I have better ROM than my body claims is available, I will get it through static stretching if needs be. Does this detract from my workouts? Possibly. Do I notice? No, because I'm not in the top 0.001% of athletes for whom marginal gains/losses of stability recently associated with static stretching would be noticeable.
It's very easy to get lost in internet hyperbole (I do it relatively frequently) about a specific thing that will help another thing, when in actual fact the basics of training/working out are consistent for everybody and never really change. Me doing muscle snatches, or paused hang snatches, or scarecrow cleans, or trying for an even-more-upright torso on back squats is all great, but do nothing for the fact that:
- I'm still not that strong;
- My fundamental Olympic lifting technique is only "ok;"
The point being that whilst each individual has specific training requirements and enhancements that can be identified through analysis of their anatomy, coordination, etc., almost all of them need fundamentals like strength, good pattern, mobility.
So whilst static stretching might impact upon certain movements, and compromise something somewhere for somebody, I'd rather you get your mobility sorted and squat to parallel (in the current instance) and then awesome depth without pain, rather than trying to squat to a perceived level and making yourself miserable.

In short: stretch. Lots.
