agreed, when you build pipelines that fail, you won't get the error anymore at
link time but at preroll.

The problem is that we're talking about hundreds of milliseconds (if not whole
seconds in some setups) of speed gain setting up pipelines with many elements.

So it comes down to "do we prefer to have faster preroll for virtually all
pipelines, or do we prefer to have early abort" ?

BTW, running the pipeline you mention does come up with a pretty good hint
(last line):
ERROR: Pipeline doesn't want to pause.
ERROR: from element /GstPipeline:pipeline0/GstAudioTestSrc:audiotestsrc0: Could
not negotiate format
Additional debug info:
gstbasesrc.c(2757): gst_base_src_start ():
/GstPipeline:pipeline0/GstAudioTestSrc:audiotestsrc0:
Check your filtered caps, if any
