Html accesskey for ion-tab

I am coding a web app in ionic. It is not going to be hybrid. It will only be used on desktops.
Hence I would love to add keyboard shortcuts (a.k.a accesskey)
w3school page illustrates accesskey usage

I shall need it on many elements, but I start with ion-tab.

It does not work in a sense that when <a class="tab-button… role=“tab”…> gets generated, accesskey attribute s not copied over.
So questions

  1. why accesskey is neglected? (I guess it is because you don’t need it on touch devices, which is what ionic is about)
  2. is there a way to make it work?
  3. is it on the roadmap?
