I understood that part; I meant whether running the ChromeOS widewine library on regular distributions is just a version difference in glibc, which would go away with time making the article's hack unnecessary in the future.
I see what you mean! I guess it depends on when Google updates to glibc v2.36, presumably they then would just include the DT_RELR version dependency on their binaries rather than unnecessarily patching glibc. Who knows how long that will take though since glibc v2.36 just came out a few months ago.
