For a11y I don't know what is seen as the major problems, is there some

the fundamentals ok and its a matter of a general malaise. Is the
general widgetry ok, but particular components have poor document level
a11y. Or is there an endless amount of fairly easy entry level problems
that there isn't enough people to take care of.
It's a bit of both I'd think.
The main issues I can think of from the top of my head are:
* Only on-screen elements of the document are exposed to ATs. This is
on purpose probably for performance (not sure if we have any numbers to
base it on?) so elements are lazy-loaded and destroyed, but it has
non-trivial impact on various AT features. There are some things
supposed to help mitigate the issues (like flows-from and flows-to
relationships), but they present their own sets of issues (like some
elements from there not having proper parent/child relationships, etc.).
* Some parts of the document are not accessible through the keyboard,
like e.g. embedded objects, images and such, which makes it nearly
impossible to AT users to interact with them.
* Some relations are missing, like for annotations and footnotes. Also,
there is a lack of semantics for change tracking leading to messy output
from ATs. These could be seen as smaller and simpler issues, as it
likely only requires plugging in the correct cables.
I don't have a comprehensive overview either, but I think most of those
have a proper bug for them.
I'm CCing Joanmarie which might have a lot more insight here.

IIUC, the gtk4 VCL plugin currently doesn't have an a11y implementation
yet, and there has been a change of how a11y is handled at least within
the Gtk library itself. [1]
Yeah, for GTK4 there will likely be a need to a whole new a11y VCL
layer. This might not be so hard to get started getting inspiration
from GTK4 itself, but a lot will have to be ironed out. Currently GTK4
itself still has a fair bit of rough edges because of this change, even
if the end goal is to make things easier and more modern.
