@vlotorev:matrix.orgHi, nodepool static documentation <https://zuul-ci.org/docs/nodepool/static.html#attr-providers.[static].pools> states:17:37
> When providing different labels, it is better to have one pool per label to avoid requests being queued when one label is at capacity.
Could you please elaborate on that?
If I have `centos7` and `centos8` labels should it better locate nodes for these labels in separate pools?
Otherwise (nodes for both labels in one pool) exhausted `centos7` nodes can block `centos8` nodes from being allocated?

This is how I read it, but I'm not sure why that is the case. Maybe a driver implementation detail
