Hello Jost,

Thanks for researching this! In fact, Arnaud did his own research on this
topic and submitted !1309 [1] to switch to the absolute paths. The MR has
been approved by Ben swiftly and now awaits merging.

I believe we should default to the common case, which is to use abs paths
making the life of, presumably, many people easier, and let those who
understand submodules hack their way through them.


Best wishes,
