Yes. My clients run Macs for security and only XP within Fusion for very old specialized software for one industry. Once their Windows XP PCs died, they couldn't install WinXP on new PC hardware for obvious reasons (drivers etc).
These clients are all-Mac shops in order to have better online security and they only use XP for a zero-internet very specialized db. My clients who use that 1990s odd program all know each other in that industry and they'll all probably retire within 10 years. They bought the last release of Intel-based Macs just for this purpose, and they know that if their Intel Macs die they'll get used Intel Macs online (eBay, Macsales, et al.).
Some of my clients who still use that 1990s specialized db software use Crossover or Parallels to run Windows XP.
WinXP runs better in Fusion in an Intel Mac then it ever did on PC hardware, perhaps because I allocate XP's max RAM (not very much) and several cores to their virtual machines and there's literally nothing else installed in WinXP.
I've kept XP running on Fusion since it came out in 2007 or 2008, I think, after moving most clients from Parallels in 2006 or 2007. Fusion and Parallels are both fine, now, though. Most of my Fusion and Parallels customers use it for QuickBooks and Quicken for Windows (they hate the Mac versions of those).
If new versions of Fusion drops XP support, my clients will just keep old versions of Fusion +WinXP running on Intel Macs only used for that purpose, i.e., no online use.
Ironically, these very confidential databases in WinXP are more secure than modern/online competing products and services because all these Macs use whole disk encryption (FileVault) and the Macs have very long user passwords, encrypted TimeMachine backups and encrypted online backup with extra security keys and mostly importantly, zero online access through the vm. I'm pretty sure all the online versions of similar software have been or will get hacked.
I'll download Fusion 12's DMG and keep it for future legacy use; my clients all keep their Fusion license keys in text files.
Amazingly, Microsoft still allows activating XP still via their phone option followed by texted follow-up option, which allows easily saving the coded box-entry values for future reactivations. Microsoft probably does this because many point of sale devices ran WinXP way way past EOL; poking a special registry key in an WinXP box made it into POS version (KEY_LOCAL_MACHINE\SYSTEM\WPA\PosReady) from MS's point of view and prolonged security updates for years past normal EOL, though even that's long gone. Many ATM machines were based on WinXP way, way passed XP's official EOL (the horror, the horror).
