Although I see that in vSphere: “
Configurations exceeding 40 virtual machines per host are limited to
cluster size no greater than 8 nodes.
“

Was this an undocumented limit that existed all along?

What VMware document tells us there was previously a limit of number of VMs per HA host? I've always gone by the Configuration Maximums document which said we can have 170 VMs per host. No mention is made that the number of VMs per HA host is significantly lower than 170. I hadn't seen a VM per HA host restriction until vSphere where we're limited to 40 VMs per host in clusters with more than 8 hosts. I am concerned.
