This is quite easily fixed with a little utility function that checks if the
remainder after parsing is a floating point or integer suffix.

However, it is potentially a nasty subtle breaking change as it's quite a
common pattern to rely on functions like "to" to check for unusual input, which
this would change the definition of. It also introduces a difference in
attitude between "to" and "parse", which currently work together very neatly.

On those grounds, I'm against it.

To be acceptable it would have to be enabled with a template argument (an enum
with names RAW and D_LITERAL_AWARE ?), or be in a function with a different
name.
