That page is about coastline, which is high water, not low water. But
you are probably right. In the case of the UK, there are proxies like
admin boundaries which help a lot, and the OS have been good enough to
survey all this coastal stuff, but there is no way of tagging a line
with "boundary=lwm" or whatever. Should it be a tag on a way, similar to
the way the coastline is tagged? Or should it be a huge relation, like
the admin boundary of the United Kingdom?
