Here it is to disclose affiliation, which else people would forget to check due to nature of 'battle'.

Also, there is an assumption that the signature contains up to date information and/or does not change over time. The latter situation would else impact historical purpose. The signature has changed and does not refer to the position/information related to the moment of writing.

I agree with how both jwildeboer (Jan) and shykes (Solomon) approached this. Much appreciated in this case.

But yes, in a normal situation, this is irrelevant and the username signature is sufficient.
