Requirements for specific version of pyserial and pyserial-asyncio dependencies?

[Hedda]

The problem

Not an actual problem today, however, wondering if it has been discussed if Home Assistant core should really pin specific versions of pyserial and pyserial-asyncio as dependencies, currently particularly in effect for ZHA, Serial, and acer_projector integrations?

homeassistant/components/acer_projector/manifest.json
homeassistant/components/serial/manifest.json
homeassistant/components/zha/manifest.json
requirements_all.txt
requirements_test_all.txt

Might it be a good idea to change from == to >= in order to only set requirements for minimum versions of pyserial and pyserial-asyncio dependencies instead of pinning to specific versions of them?

"pyserial>=3.5"
"pyserial-asyncio>=0.5"

Backstory; Noticed this when PR #44089 by @Adminiuga was merged as it bumped to to newer pinned versions of these, from pyserial 3.4 to 3.5 version and pyserial-asyncio 0.4 to 0.5 version, as a requirement in Home Assistant core.

Hey there @dmulcahey, @Adminiuga, mind taking a look at this issue as its been labeled with an integration (zha) you are listed as a codeowner for? Thanks!

FYI, apparently, the bug reported in pyserial/pyserial-asyncio#69 for pyserial-asyncio 0.5 version breaks it from working in Windows.

Slightly off-topic but maybe consider downgrading back to pyserial-asyncio 0.4 or include pyserial/pyserial-asyncio#70 bug-fix?

HA requires all integrations to pin specific versions, so no to >=

[fabaff]

Well, technically it is not a "requirement" of Home Assistant. It was a decision to ensure that integrations keeps working even if upstream projects introduce breaking changes. For me the pinning is/was one of the QA elements we have. If I update a dependency then I run the integration. Thus, I'm able to say that to a certain level the integration works with the configuration we provide in the documentation and the release we are pinning.

OK, thanks for the answers. Closing this.
