Glad it's not the funky mobile field workaround. That's such a horrible
experience for developers that even the act of documenting it should
have been a red flag to go back and refine the field buffering for the
few cases where that put-it-in-a-group recommendation is actually needed.
In your case, you have a huuuuuuge canvas, with users expected to scroll
a region about 32 feet. That's a lot of scrolling.
So in addition to the memory hit of buffering such a large region (32767
* 32767 * 4 + whatever other overhead comes into play with buffering),
in most layouts it would be a usability impairment to ask users to keep
scrolling that much.
So maybe the team could switch the address from 32 to 64, but it still
leave us with the question:
- Would a user have that much RAM?
- Would the user be able to use such a large canvas without acquiring
RSI? ;)
I don't know your layout, but I do know you, and you're not the type to
make things hard for users, so I'm assuming there's something about this
uncommonly-large scrolling that fits well with the app's requirements.
But what we do know is no monitor can show it all, so the content is
already effectively paged into view as-needed.
Could the content paging be provided through some other UI? For example,
if those controls fit into logical groupings, might different sets of
them be placed into separate physical groups, perhaps accessed via tabs
or a list?
If it's truly necessary to have one vast plane to hold everything, could
you handle paging internally while still providing the appearance of a
contiguous group, similar to how the DataGrid does it?

Is this for the weird recommended mobile workaround of putting a text
field into a group just to have it scroll, or something else?
