I agree with a lot of this. For 1500 users in the financial org, pay for systrack/loginvsi to benchmark/profile - particularly if its lift/shift. Alternatively dedicate storage/platform to suit - 99.95% of VDI deployments fail based on storage performance. HCI (VxRail, VSAN, Nutanix, etc) works great here, particularly for building pod architecture. Infact if you're not buying infra - or don't have *high* end kit like VxBlock / NVME-primary storage and Gold/Platinum Ghz focused CPU's - probably abandon ship. I'm genuinely skeptical that WVD can provide a great "power user" experience cost effectively as well. 110% - bench mark it, and use something like HCIBench to prove on your POC cluster that it will handle it. I would almost say its pointless in 2020 to do VDI without GPU/NV Grid. Agree - you will literally tear your hair out here. This depends entirely on enterprise maturity and strategy. Sure a bunch of people are on the M365/AzureAD train - which removes a lot of traditional soe requirements, but many orgs are not willing to give up years and hundreds of GPO's - and VDI will be a good fit for them for a while to come.
