Why dell.powermax 4.0.0 does not support PyU4V 9.2?

When we try to install required dependencies for dell.powermax 4.0.0 with PyU4V 9.2.1.7 we get error that it could not find a version that satisfies the requirement pyu4v==10.2.0.*,==9.2.1.7,>=10.2.0.3.
When I look at https://github.com/dell/ansible-powermax/blob/main/requirements.txt it looks like you have removed support of PyU4V 9.2.x.
Why you stopped support yU4V 9.2.x. when there are many PMAX 2k & 8k systems are still actively used in PROD?
