Why spaces for NANPA? This is very unusual. Is that written in a standard

actually would be confused seeing spaces.
Agreed. If the intent of E.123 is to format telephone numbers for human
readability, it should do so in a manner that is consistent with the existing
convention for humans in the country where the number exists.
For NANPA, the National format would be (NPA) NXX-XXXX or NPA-NXX-XXXX. If
other countries typically publish phone numbers using other punctuation as
separators such as dots or colons, then use those for that country's National
format. For International, the use of spaces makes sense.
Exactly this.
The ambiguity for NANPA is that it is country code 1 and the local convention
is to use a leading 1 for "area code follows" to differentiate from a 7-digit
local number in those locations where 7-digit dialing is still in use. That
ambiguity really doesn't affect the digits input, however. When dialed en
banc such as on mobiles with a SEND button, the leading 1 can usually be
omitted with no effect on the call going through.
If a NANPA resident sees a phone number with just spaces they're likely to
assume that it's an international call.
The goal is for the library to offer choices made by the implementor to
decide what is best for the end user.
A US-only or North American-only App or Website would use the National
Format, (NPA) NXX-XXXX or NPA-NXX-XXXX.
Apps that span countries, such as North America, Central America, South
America, Europe, Asia, etc, would use the International Format.
The problem is that the International Format provided by libphonenumber
for NANPA, Ecuador, and Argentina, are a hybrid of International and
National format, rather than following the International ITU convention of
only using number groupings and spaces with the leading plus sign.
