Hi Hǎiliàng:

"there is no plan to change" is a literally correct summation of what
I said before, but I also emphasize now (if it wasn't clear before) I
would like to see such a plan developed because integer widths for
plwid are just too much of an API limitation these days.

I think what we should do is deprecate plwid(PLINT width)
and write a new function declared as

void plwidth(PLFLT width);

I will contine this discussion further on the PLplot development list.
