Indeed, it works theoretically but, in practice, it is going to break documents written by taking advantage of the fact that \input@path was being being defined by LyX. See the use case about fontspec in bug 6634.
I'd say this is just life. \input@path was not documented and we are not supposed to keep all ERT working forever.
In this specific case, we should also manage a TEXFONTS prefix. Maybe we could manage a single prefix, say TEXPATH, and use it as a prefix for all relevant environment variables used by TeX (TEXINPUTS, TEXFONTS, BIBINPUTS, ...)
Reading the kpathsea manual, I found: 3.3.5 KPSE_DOT expansion When KPSE_DOT is defined in the environment, it names a directory that should be considered the current directory for the purpose of looking up files in the search paths. This feature is needed by the ‘mktex...’ scripts mktex scripts, because these change the working directory. You should not ever define it yourself. Is this what we are looking for? JMarc
