Is Dirac delta worth its own tag?

Dirac delta is pretty basic concept and we have multiple questions mentioning it. It also causes many confusion, so it is likely to provoke new questions among those who first encounter it. Maybe we should create a tag for it?

• Delta function is a standard mathematical object and corresponding tag exists on Math.SE (with 500+ questions). But does it have any particular relevance for statistics to warrant a tag here? – amoeba Oct 8 '16 at 19:35
• @amoeba it is used in statistics and probability and seems to cause some confusion for those who first encountered it. Moreover, in probability it can be regarded as a degenerate distribution and understood as it it provokes on-topic questions. – Tim Oct 9 '16 at 8:26
• The Dirac delta is implicit to many stochastic processes as it is the identity function for convolution. However, it would not be used alone, but always in conjunction with something else. I do not personally see any particular reason for it to appear as a stand alone tag. – Carl Oct 14 '16 at 23:33

Personally I'd considered [dirac-delta] tag useful. The question already got eight upvotes and one negative (?) comment by Carl. I'd say that the response to this idea is positive, so I'd consider creating it.
