Hosted pipeline limit
Now, we just can buy 10 Hosted pipelines, could you increase it?
It should work similar to how many Azure resource limits work currently. There's a maximum you can buy through the standard UI and anything beyond that requires contacting Support to get the increase. One common reason for this is to avoid a large purchase from impacting availability, it gives the teams a heads up on the increase.

Can anyone point me to where MS mentions this limit?
I've hit that limit and the page, where you can try to set it has a link, which is supposed to lead to a way of raising the limit, but the link is just getting redirected to the support homepage.
