Code looks good but it seems that encoding of VMTests changed and they are now failing with io.circe.DecodingFailure$$anon$1: [A]List[A]: DownField(logs),DownField(log4_nonEmptyMem)
Do you think it will be easy enough to fix it in this pr or it would require another task?

what do you think about removing the default here? it seems to make sense to force someone using this method to always pass this param

Why do you think so? I think that if Account#empty has a default argument, then logically it follow to add the default here. (And I think the defaults stem from the fact the idea of non-zero starting is considered funny ...)
