Raid 0 and raid 1 absolutely work well on btrfs, I've been running in production at scale for more than a decade.
(Raid 5 and 6 are a different story, but frankly I think it's silly that modern systems talk about them at all, instead of general purpose erasure-coding.)

Considering btrfs doesn't have a working RAID implementation, screwing up a drive would lead to the volume being unusable, yes.

Symbology devices ship with btrfs based raid by default.
Synology's RAID is based on a combination of Btrfs and MD, it doesn't employ Btrfs' multi-device support at all.[0]
