Of course. It's simply that someone has to do it (just like for LLVM).
Also, does producing CIL compliant
binaries could help the development of client side applet for web
applications?
Unlikely, because the sort of CIL that FPC would generate would be of
the "unmanaged kind". Running that sort of code would be just as
unsafe as running a random executable. Furthermore, such code would
still be completely platform-dependent: FPC (and GCC) would just use
CIL as an assembler format, but all types, system functions etc would
be specific to the OS/architecture for which you compiled.
What you would need for web applets is that additionally someone would
add a .NET-based rtl to FPC -- but in that case, your users would also
have to have the .NET runtime installed, and it would become
impossible to compile the CIL further into native code without adding
external dependencies (since the RTL would depend on the .NET
framework).
Generating CIL as intermediate code is by itself only useful if you
are interested in
a) using some other code generator that FPC's to generate the actual
machine code (but note that FPC will still require support for the
target cpu and OS that you want to compile for, because as mentioned
above the generated CIL will already be completely target-dependent)
b) (possibly) to more easily interoperate with other compilers that
can compile code into CIL
