Yes, I think. There is no doubt about increasing the importance analysing of access logs.
Some people, including me, have experiences to customise parsers after expanding combined format with several fields. It's annoying to re-write regular expressions for parsers of tools we use when changing log format and to remember the meaning and order of expanded fields.
With LTSV, parsers does not need to be modified in that cases. Easy to expand logs and easy to process them with labels.
