This would seem so according to `man dnf swap` which shows `dnf5 swap [options]
<remove-spec> <install-spec>`.
However it seems that this command does not care about the order of packages
given as arguments and removes one which is installed and install the other
one.
First invocation (removes openh264, installs noopenh264):
```
$ sudo dnf swap \*openh264\* noopenh264

Repositories loaded.
Problem: cannot install the best candidate for the job

Second, identical invocation (this time does the opposite; removes noopenh264,
installs openh264)
