Well, by the looks of it, it bundles all the deps in one archive, so you no longer depend on system ones, but also you miss out on system updates.
I use a commercial professional multitrack audio mixing package called Mixbus (derived from Ardour, but with specialized DSP for the summing and for plugins; the portion derived from Ardour is open source, the DSP plugin code is closed source, and thanks to the plugin API is not a 'derived work' since it would be usable from any plugin host.....). This is the way Mixbus is bundled, with all deps prebuilt and stashed away in the proper /opt tree.
Now, as to 'updates' specifically, yes, this puts it on the developer of the package to make sure updates that are necessary are actually applied. OpenSSL, for instance; although, I wouldn't think Openshot would use that one (Mixbus doesn't; in fact I'm not sure how it could be remotely exploited at all). So for certain things the 'bundled app' makes sense; for a server process it would not.
Mixbus works very well on CentOS 7; I use it every week for longform broadcast production and mixdown, and just running the Harrison Consoles installer script 'Just Worked' as it was supposed to (if it doesn't the Mixbus devs get a message from me.....).
Further, the official Ardour.org Ardour packages for Linux are similar bundles; at one time if you built it from source using the system libraries you were not guaranteed support or that it would even work. You run the installer script, and it just works on pretty much any modern Linux. All files, libraries, etc for all dependencies are loaded into the appropriate /opt tree (example:
[lowen@localhost ~]$ ls -d /opt/M* /opt/Mixbus-2.5_14392 /opt/Mixbus-3.1.66.uninstall.sh /opt/Mixbus-2.5_14392.uninstall.sh /opt/Mixbus-3.2.22 /opt/Mixbus-3.1.66 /opt/Mixbus-3.2.22.uninstall.sh [lowen@localhost ~]$ du -h --max-depth=1 /opt/Mixbus-3.2.22 104M /opt/Mixbus-3.2.22/bin 212K /opt/Mixbus-3.2.22/etc 132M /opt/Mixbus-3.2.22/lib 17M /opt/Mixbus-3.2.22/share 252M /opt/Mixbus-3.2.22 [lowen@localhost ~]$
Note that multiple versions at a time are fully supported, and the uninstaller is ready (and able) to run at any time. In fact, the installation script asks you one by one if you want to uninstall any of the prior versions. As you can see, I currently have three versions installed side-by-side. The installer script is in the open source portion of the program, available through the Ardour git.
It does take more disk space to do this.
And while I have always been a big fan of RPM and of always using the repos for things, I have to say that there are many things RPM packages do not do well for the most part.
