Yes it does (*), but I think it is NOT a bug but a feature,
at least for "check" and "install" (*) 
and very much desired in some cases :

For instance, the package developer may want more
regression tests in <Pkg>/tests/ :

1) Have extra *.Rout.save files that are architecture
   dependent and hence not for general distribution of the
   package, but important for the package developer in order to
   assure that functionality doesn't change when the package is
   extended, reorganized, ....

2) Have more  tests/*.R  files  that take a long time to run.
   Time that the package developer wants to spend, but doesn't
   dare to put on the daily CRAN or Bioconductor test suites.

3) similarly for vignettes

4) similar issues for experimental  R/*.R files  or man/*.Rd
   files for these.

One I thing that would be quite useful and would even solve
Gabor's problem: 
The introduction of a new command line switch, say "--build-ignore",
to the commands 'R CMD check' and 'R CMD install'


(*) I do agree that  "R CMD build --binary" probably really should
    follow the ".Rbuildignore" file ``directives'' if it doesn't
