Most of the shells I know off use the home directory, when you specify
just the relative file name ".tramp_history".

I have thought about this, when I was fixing bug#19731. Unfortunately,
there exist shells which cannot expand "~/". Other shells cannot expand
"$HOME/". So I really don't know a robust default we could offer.
Maybe one should give this problem more emphasis in the Tramp
manual. But who reads manuals?
