remove "heading to id= attribute" behavior

[davidnuescheler]

currently we are using a common pattern that translates headings to id= attributes so they can be addressed via # fragments.

i think this is not very practical in most website use cases as there is a stability requirement, so author control (mostly on sections instead of headings) is really much more desirable. also it seems that since the current behavior could easily be implemented client sided if needed it feels like extra markup that doesn't need to be transmitted.

i appreciate that proposing this change is a breaking change, but i think it could be great if we started to transition to that possibly by removing the id attributes in aem.js to make sure that projects stop relying on it.

Stripping it in aem.js seems sensible.

hi @davidnuescheler - I was wondering if theres any progress made on this ticket? I am getting continued asks about this feature on my end as we would like to have the ability to anchor to a non heading (i.e anchor to any section of the page or even a block). https://jira.corp.adobe.com/browse/MWPW-141652
