Well.. applying this logic to compiler design would result in a compiler that keeps building a binary regardless of syntax errors. Put other way, you insist on building even if the result is known to be wrong. In my opinion it's bad design, which already drove at least three users to problems. I fully agree with Erich that the default should be "abort on errors".

Well.. after *successfully* building an image nobody cares of log files. One realizes that the build has gone wrong a lot later, after deploying the broken image on the target and trying to figure out WTF is going on. This process takes *a lot longer* than aborting the build immediately, fixing the typo and restarting it again.

Best,
Lukasz
