Hi everyone,

We are in progress of adding support for CPython 3.10.
Unfortunately, some packages are pinned at old versions, which do not
support 3.10 build.  In particular, those packages are:

- PyYAML (pinned by awscli)
- pywin32 (pinned by docker)

Should these packages that hard-pin other packages for too long (in this
case, awscli and docker) be removed from the distribution?
Alternatively, could this issue be resolved gracefully by asking the
upstream developer to remove these pins?
