Like them better than the standard way of drawing 🙂 They seem more similar to the real parts when looking at SMD transistors.
No ...it was an older convention of drawings i saw also on old Philips , Saba or Telefunken , eastern european , german and even some japanese germanium radio schematics .I's rare but it was spread all over the world...I think I even saw it on a NAD official schematic.
I have not noticed it in Philips publications; nor old Japanese. Little access to Eastern European here.

This page has a paste-up illustration with both types of transistor and both symbols.
"The Swedish standard institute (SSI) symbol, from 1965, is depicted below the junction transistor. It turns out to be a bit more of logic behind that one. The base “cuts” the emitter and collector and the current goes straight through the base. However, the symbol lost the battle."
We don't make Junction transistors that way today (not since around 1965), showing the futility of basing the symbol on the part as produced.
In my eyes, the particular advantage of the other symbol is that it sketches easily. We can't draw orthogonals neatly, diagonals never go right, especially if you want them to bend 45 at a circle (which is never sketched round). A cross, a V at emitter, and optionally a circle which does not have to hit any special point... wonderful to hand and eye? But from lack of practice, I can't read it like the bogus Point-Contact based symbol.
