Pretty much so yes.

No, I don't think so. Honestly. 

Or, as always, it depends :). Mostly on hat is considered as hard
parts. Adding missing stuff to CL is most volymous dull labour but
conceptually not very hard. There are some nasty spots like implementing
elisp reader for character handling. It was quite annoying since
character handlign is mostly just a wrapper over C and quite
inconsistent in Emacs, so it was lots of cases to cover and lots of
testing, but logically it was not a problem that needs some special
thinkering to solve it or so, if I am expressing myself clearly here
