Yup. Sounds reasonable. Although we should not use it blindly; just
where necessary. Checking for element at point will create overheads.

May you please elaborate?

I recall struggling with it and ending up with adding spaces manually to
the first src line and then using indent-region.

`indent-line-function' technically allows force indent, if
`tab-always-indent' is set to t, but we have <TAB> bound to org-cycle,
which will take precedence when at #+begin_src.
