I am not sure if email - "2u-arch-bom@edx.org" exists. Need this confirmation.

I don't think it does. But thinking on this more, shouldn't dependency-related alerts be going to Orbi-BOM? Like this: https://github.com/edx/edx-arch-experiments/blob/0b959f3976b2be7ea3dfe328f4a64905f1914498/.github/workflows/upgrade-python-requirements.yml#L18

@timmc-edx
I am not sure if having orbi-bom as reviewer will work as orbi-bom is not cc and wont have merge rights for these PRs. Not sure if you are suggesting something different here.

Ah right, I forgot the difference in orgs.

Let's use this address: https://github.com/openedx/edx-django-utils/blob/f3566ac92a34a87e83e0935d5fd57a16b408dad9/.github/workflows/upgrade-python-requirements.yml#L17

@timmc-edx changes are in there, can you please approve and merge?

[timmc-edx]

Looks good. We'll have to look into this dependency/test issue at some point though...
