ARM development at Cloudflare is still quite active:
https://blog.cloudflare.com/porting-our-software-to-arm64/
although it sounds like they've had more teething issues due to lack of availability for native arm platforms and flaky emulation so they are stretching out their transition a bit.
It is not at the very top end of performance where the power usage of just the CPU factors most into system level power draw (rather than interconnects, memory or storage). Qualcomm is aiming for a knee of the curve with Falkor and its followup that Intel's bread and butter cores can't currently reach; they still have their Chinese JV for further iteration but as mentioned before, they can still reap most of the benefits with the existing cores piggy backing on the industry leading TSMC / Samsung process cadence. Intel's process is now at parity with the rest of the industry; their margins are being gradually choked off and this will affect their ability to transition in the future.
