If you look hard enough, streamfab brands the FFmpeg with their own signature 'DVDFab Software Inc.'

They are just "touching" the file, just like they do with the date on all files being the date of release.
still wonder if updating mp4box is needed, but it never hurts to update it to the latest.
Of course, it is needed. From what I have read, MP4Box is the preferred remuxxer for MP4 for people in the know. If it wasn't for the 702 issue, your thought of getting rid of MP4Box would never come up. Someone needs to notify GPAC of the problem. They are actively working on the 2.5 series as we speak.
Streamfab browser needs an update as well, badly, as more reports are coming in with people not being able to log into their services, which is almost always a sign of old browser versions.
No, CEF is not that old. What is it, 131, now? The latest release is 136. To be honest, most of the newer features in Chromium are just fluff anymore. None of it winds up being in SF. Security fixes are certainly welcome, though. I'm familiar with a renaming program that also uses CEF. It uses CEF 106. Granted, the browser is just used as a display for online databases such as TMDB, TVDB, IMDB, and TVMaze. Very simple stuff. And the kicker is one I did not know about until moments ago, the excellent downloader Tubedigger, only uses the 93 version of CEF. To me, that shows that downloaders and other programs don't necessarily need the latest and greatest.
As of yet, updating mkvmerge seems to make little to no difference, even though it's a huge version gap from the one in streamfab to the latest (68 to 92). But again, it would not hurt to update everything.
The only thing I see that has been added to and improved on in later versions and affects us now are Chapters. If you are using Amazon Prime and care about Chapters, it'd be in your best interest to update. For almost all the new features otherwise, a lot of it pertains to new and emerging codecs and formats that eventually SF, hopefully, catches up with. It is surprising that 68 has held up for so long, but why keep it that way when it is so easy to update it.
I also found most of the other downloaders, some called recorders, don't even use mkvmerge, they just use FFmpeg.
FFmpeg can accomplish, making both mp4 and mkv files.
As you know, recorders are totally different animals. No other DRM downloader actually downloads the audio and video files as found on the streamer server as SF does. Most record the combined display signals from your computer. They can get away with not using specialized apps because accuracy is not as important. No, I'd like to see MP4Box, MKVMerge, and FFmpeg all working at their full potential within SF. It's just a matter of getting the bugs fixed.
And of course, keeping their branded version (YoutubeToMP3Process.exe) of yt-dlp updated always helps. Then they can also brag, look at all the more sites that streamfab (yt-dlp) can support.
