A wild guess:  maybe your implementation of |\pdffilesize| doesn't try
to guess the extension as |\input| does, thus the difference you are
seeing.  Because as others have already said, |\input{docstrip}| works
in both older and newer (web2c-based) LaTeX.

Sorry if this isn't useful:  can't run any code right now.

Best,
Phelype
