"Share/HTML" leaves away those features. It would be nice if they either
*were also included in the code and shown on the embedded map OR
*if the user of the "Share/HTML" feature would be informed that those features are missing. For example by changing the currently shown info text "Paste HTML to embed in website" to: Paste HTML to embed in website. Note that only the current map dimensions and the layer selection will be transferred to the produced HTML code

I'm not at all sure we want to allow this to be honest - it's potentially very dangerous from a load perspective if somebody uses it to stick a map somewhere that has a large and complex relation on it.

You mean accidental DDoS of osm.org? hmm...
What about changing the text for now? It is only shown if somebody really clicks on "HTML" - so it is not cluttering the sidebar (I guess showing the text only if the current URL contains a not supported feature parameter is too much overhead). Or want we want to just forget that use case for simplicity?
