Hey @robbycochran - I've reviewed your changes - here's some feedback:

Overall Comments:

• This revert removes ARM from the unit test matrix; confirm if this is the intended behavior.
• Building ARM images on amd64 runners using emulation might significantly increase build times compared to using native ARM runners.

Here's what I looked at during the review

• 🟢 General issues: all looks good
• 🟢 Security: all looks good
• 🟢 Testing: all looks good
• 🟢 Complexity: all looks good
