I think folks seeing a build number may feel uneasy with it at first because it's new and different but after a time I'm not sure it would be any more confusing than parsing what 1.2.0.4 would mean.
I take comfort in knowing the patch message's claimed build number and executable file version match. I used to go to c:\program files\Sony\Vanguard\bin\VGClient.exe and see the file version (right click properties -> version -> File Version) match the build number. B) I know i have the right version EXE all least.
I now have the file explorer set by default to display file version details so it just pops up now.
