This isn’t something inherent to SPAs, though sadly many (most?) do omit the history api and don’t provide usable URLs nor back/forward navigation.

[pimlottc → xenic]

It's somewhat inherent, as the URL will not change by default and it generally takes an intentional to implement sharable URLs.

"Somewhat inherent" isn't meaningful or correct. The fact is that there is a history API and you can use it to implement history for SPAs. Therefore, lack of history is not inherent to SPAs by definition. Intentionality has nothing to do with it.
