It probably depends on the person. There are controversial debates on this topic all the time on r/learnjapanese.

In my experience, stopping writing practice has made me progress faster with Japanese, since I can now use the time for other things.

I do think that learning to write the first 400 or so did help with drilling down the basic shapes and developing an eye for the characters.

It still takes a lot of (just visual) repetition with Anki though to really remember new ones.

I've heard from people who have great difficulty learning the characters this way, and maybe for them practicing writing could be helpful.
