Do lightweight transactions support delete statements, if exist?

Question

I read that lightweight transactions simply support update and insert statements with the "if" and "if exists" clauses. Do they also support the delete operator with an "if exists" clause.

For example: create a table user (user text, message text, primary key (email))

remove from user where userid = 'kris' if exists

Do lightweight transactions help the above delete operator?
