Yes, TS was initially intended as transport format for broadcasting 
services, but since you can simply include useful meta informations like 
SI data, recording timestamps, teletext and subtitles into your 
recording by simply enabling the appropriate PID filters it is 
well-suited as archive format too.

The 'real' format that was intended for archives was probably PS, not PES.
