probably not that useful to have on these days, most people just use mempool.space for that. I like it for querying random txids and doing stuff locally.
Discussion
so if i turn that off i wont be able to use my local instance of mempool?
not sure how mempool works, just referring to bitcoin core
if you run your own instance of mempool, it requires bitcoin core and electrs as dependencies.
Once running your ow instance, you dont have visit the website and just use mempool space locally on your own node.
If turning of txindex will disrupt this, ill just get a new 4TB NVME
