Nice example!

I tracked this down to 1. as_variable being called when extracting the index. This seems sensible. https://github.com/pydata/xarray/blob/21705e61503fb49f000186c0d556e5623bd5ac82/xarray/core/merge.py#L413-L420 2. as_variable being called again in the expand_variable_dicts call in merge_core (should be avoided): https://github.com/pydata/xarray/blob/21705e61503fb49f000186c0d556e5623bd5ac82/xarray/core/merge.py#L493-L497

We need to replace the appropriate objects in aligned with IndexVariables from indexes if indexes is not None.
