LEDE does not use svn.

They are probably worse. ;-)

I think we should encourage everyone to upstream the patches, I think in
one of the statics I saw that OpenWrt ranked 3. or 4. in contribution to
the kernel among the Linux distributions before Canonical. ;-)

Only allowing upstream patches also conflicts with the goal to be more
stable and not always use the most recent kernel which introduces new
problems again.

Some kernel patches are also directly extracted from some other
repositories or from some vendors. The raspberry pi patches for example
are exported from some other repository.
