A very popular topic title on this forum seems to be “Taking ABC seriously”, just use the search on this forum and enter “Taking seriously” and you will see a large list. Although a lot of interesting and fruitful discussions have resulted in these topics, I personally think that this is not a good way to start a topic because is implies that whoever has done the previous implementation of ABC was not serious about it. So at least in my non-native english mind this creates an overly negative picture of the previous work.
I would suggest to use rather neutral titles like “Suggestions to improve ABC” or “A more coherent way of implementing ABC” etc instead, or to already mention the exact point to be improved in the title. This would give more respect to the previous work and does not imply people were not serious about what they were doing.
