Without workarounds a lot of stuff couldn't be done in Limesurvey. So I think the workarounds are VERY valuable. If something is a very rare case, workarounds can help to get to something that probably will never make it to core, because it is not worth it implenting, because only very few need it. So the possibility of workarounds are great.
However, if certain workarounds are in a high demand, they should move from workaround to core. Especially that "normal" users often are not able to implement workarounds (no access to the template, no possibility to use Javascript, etc).
