New submission from Serhiy Storchaka :

They were added in 436c3d58a2570f3b599e59b4071f944f774ec441 (between 1.6a2 and 
2.0), but the purpose is not known. See also 
https://mail.python.org/archives/list/python-...@python.org/message/DVSQGM5LO4TK63C63H6KQ6XBTBQGFLEN/.
 The feature was not fully implemented, and it was disabled short time later in 
29c4ba9ada44d62988c62c85c8046985f10a1c85. Currently the only effect of this 
flag is that repetition operators (+, *, ?, {}) do not work. A comment was 
added in 3562f1176403653ebfbef6275d449ad42d1b843a:

SRE_FLAG_TEMPLATE = 1 # template mode (disable backtracking)

It's all. I guess it could have some relation to possessive repetition 
operators, except that it is a global flag.

I think it should be removed without deprecation because it never really worked 
and never was documented.
