Another practical concern: Lennart is developing a lot of new stuff, supposed to sit at the core of a Linux system.
PA, systemd, bluez, now this, was there more ?
Every piece you write you have to maintain in the future. Even more so for such core tools. This adds up.
Will Lennart be able to support and maintain all the things he has developed (and will develop if it continues like that) in the next 10 or 20 years ?
