Yes it got pulled as you can see here:
https://developer.apple.com/safari/download/
Although it never showed up in the App Store for me since a few versions ago on three different Macs (two got even a few clean installs without backup import in the meanwhile). Even the High Sierra betas sometimes don't show up and I had to download the full installer.
I always check that website every day after a new High Sierra beta had been released.
On all Macs the developer beta access utility was installed.
Still no crash with 39 on my Late 2011 MBP. Didn't test it on the other two Macs yet.

On my iMac there is also still iTunes 12.7 (running fine) what I never got on the other Macs. It had been pulled months ago shortly after release and never came back.
