Hi @BethGriggs, can you give this a quick look? Just need a sanity check, prefer not to approve and merge my own PRs.

lol @ "minor breaking" changes which are not considered major :P

It's not yet 1.0, I'm following this: https://github.com/backstage/backstage/blob/master/REVIEWING.md#reviewing-changeset-bump-levels

[vinzscam]

shall we ship as a major? It could make sense

[awanlin]

I would prefer to keep following the conventions I've been following so far.
