But no new forks arised since i began to compete with you.

cdrkit is the fork by Debian. Last release was in 2010.
Now look at contemporary Debian ISO images:
dd if=debian-7.0.0-amd64-netinst.iso count=100 | \
strings | fgrep XORRISO | sed -e 's/ //g'
XORRISO-1.2.6 2013.01.08.103001, LIBISOBURN-1.2.6, LIBISOFS-1.2.6, LIBBURN-1.2.6 2013050414444100

If not for technical reasons then for the fact that mkisofs has been
thrown out of major Linux distros. (Expelled for social incompatibility
of distro maintainers and you, to be clear.)
MD5s ? ACLs ? zisofs ? File filters for encryption or compression ?
Support without accusations towards users ?
But of course one does not need growisofs, because xorriso can burn
to all the media which growisofs can burn.
I learned a lot from growisofs. Chapeau towards Andy Polyakov.

My stuff burns CD, DVD, and BD on Linux, FreeBSD, Solaris.
On Linux and FreeBSD it needs rw-permission for the device file.
On Solaris it needs pfexec privileges "basic,sys_devices" and
r-permission for the device file in /dev/rdsk.
On Linux, you need superuser privileges only for SCSI commands
which are not listed by the kernel as legitimate commands.
All MMC commands are allowed. Also all commands from SPC and SBC,
which are needed for MMC drives.
Not allowed for normal users are the manufacturer-proprietary
commands which are issued by the quality checker QPxTool.

Impressive. Chapeau again. (But where shall i get an Apollo MC68000
machine ? They were really nice, back in the early 1990s.)
Most user feedback about libburn comes from Linux.

Having had a Unix life before Linux, i know how to write portable C.

Not with GRUB2 script grub-mkrescue. I added several features
on request of Vladimir Serbinenko (and killed the GRUB2 fork of
mkisofs before it could get released).
Further Vladimir contributed code for HFS+ hybrid filesystem.
It is about production of MBR, GPT, and APM, for the purpose
of booting from CD and USB stick by BIOS, EFI, and Apple firmware.

The users have the choice ... if their distro maintainers
aren't refusing to package cdrtools, that is.
Have a nice day :)
