Great. It's only really relevant for Jack apps under Linux.

It does however solve problems with loss of precision when need to
render soft synths to disk, bounce tracks and re-import, or apply
offline effects as well.
The point is moot anyway, as all the Windows sequencers let you work at
32bit float if you like.

It works, is easy enough to use, offers enough features and is reliable
enough for me to consider it an alternative for audio to Cubase.
Believe me, for a Linux sequencer, that's significant. For Free
software with open file formats, it's very unusual.

There's thousands of other audio programs, from softsynths to
forensics, but you will have to tell me what you consider to be a
significant application for me to pick examples.

I guess there is Rewire on Windows which lets you run some subset of
Rewire compatible applications synchronised at sample level, but it's
quite limited compared to Jack.

That's 'peculiar' as in 'belonging distinctively or primarily to one
person, group, or kind'.
Windows apps don't share the same code or a common sound server to
perform this task, and so peoples experiences of reliability with
different combinations of sequencer software, drivers, sound cards and
computers vary greatly.

Witness the bizzare and unaccountable flaming from advocates of various
Windows sequencers on this group for examples.

That was a joke the various Windows audio 'standards' and free software
developers. It does not bear explanation.

I guess there are also the EchoAudio, Digigram, SEKD cards, and a whole
heap of consumer ones and USB devices. How many cards do you need?

Nah. 32bit float is just the format the files are stored in.
