One solution/workaround is to use permanent block id together with editable/changing header.
Then the references do not need to be updated so such header can be edited in any application.
## experimental header 1 ^id1
The up-to-date header can be displayed in place of reference using either Obsidian style [![[#^id1]]](#^id1) or markdown style [](#^id1) transclusion. (tested, both work in Obsidian 0.9.20)
This works best with Inline transclusion.
This does not transclude whole chapter but the header only.
