That's pretty much Microsoft's approach on every system now - even if you install Outlook or Teams, it's just a web app. If it weren't for that I wonder if keyboards on iPads would even still be common at all. That said, there is a heck of a lot more to enterprise apps than things like email still out there. When I was still at a health system we'd try to use tablets for new things whenever possible (they are just physically convenient in many work environments) but we'd inevitably end up with "web stuff" on the tablet and "everything else" on a laptop (sometimes with mobile cart) for this exact reason.
I also worked in B2B health SaaS companies. Even then some health systems used whatever you call the hosted Windows servers and people used their computers as dumb terminals to run apps. There were clients for iPads.
This is an option for a lot of things, e.g. we delivered Epic Hyperspace over Citrix, but it can be extremely expensive in terms of TCO to do for every app (we still had over 3,000+ individual on prem hosted apps maintained).
