Thanks, Arsen, for this information.
Are there any statistics on the number of mailservers/... requesting SPF records instead of TXT records?

Just take into consideration the ongoing IETF discussion about obsoleting SPF RR.
12.1. The SPF DNS Record Type
Per [RFC4408], the IANA assigned the Resource Record Type and Qtype
from the DNS Parameters Registry for the SPF RR type with code 99.
The format of this type is identical to the TXT RR [RFC1035]. The
character content of the record is encoded as [US-ASCII]. Use of
this record type is obsolete for SPF Version 1.
IANA is requested to add an annotation to the SPF RRTYPE saying
"(OBSOLETE - use TXT)" in the DNS Parameters registry.
