Plugging blow-off valves?

hello all, this is somewhat of a controversial topic, but I wanted to know people's opinions about plugging the BOV/DV to get the famous/infamous turbo flutter. I already have my own opinions on the matter, but I'm just curious as to what other people on this forum have to say on the topic.

Doesn't the BMW have a recirc and not a BOV? I forget, since I don't own one anymore.

When it came to the BOV on my subie, lots of people thought you had to install a different BOV to make a loud PSSSSSSHHHH sound, but the reason you don't hear it is because if the intake silencing. Put a short-ram intake on there and it's loud as can be, you hear it all the time. Heavier duty BOVs are needed when you put a bigger turbo in there.

My b58 has no BOV.

So I guess Compressor surge is overrated. Lol

X2 m35i has a bov but regular b46/48 doesn’t. I am guessing it’s dependent on the boost running. 14psi, ok, 23, no.
