Neat trick python!! You could hide the prefix-list and groups or the matians using pythons trick!!!
set groups TKI interfaces <ge-*> unit <*> family inet filter input TK1
set apply-groups TKI
set policy-options prefix-list TK1 15.10.1.0/26
set policy-options prefix-list TK1 16.10.1.0/26
set policy-options prefix-list TK1 168.10.1.0/26
set firewall family inet filter TK1 term 1 from prefix-list TK1
set firewall family inet filter TK1 term 1 then discard
set firewall family inet filter TK1 term 2 then accept
user@srxD300# show interfaces | display inheritance
ge-0/0/0 {
description "MGMT Interface - DO NOT DELETE";
unit 0 {
family inet {
##
## 'filter' was inherited from group 'TKI'

filter {

## 'input' was inherited from group 'TKI'
## 'TK1' was inherited from group 'TKI'
##
input TK1;
}
address 192.168.1.138/24;
