Just as you rarely see people with swords nowadays, so krises are mainly kept as heirlooms and works of art. Traditional blacksmiths are now rare fir obvious reasons, and using the rarity of krises now to dispute their commonality then is like saying that swords were never common because only the rich or distinguished officers have them today.
The Kris remains relevant even in today's world as a symbol despite its rarity. Years ago, a storm was raised over the waving of a keris by a Malaysian politician at a rally, leading to accusations of Malay supremacy being espoused
now, there's a difference of culture here. In indonesia, 80 to 90 percent of the people still live in medieval way of life, there is no reason that their krises is thrown away because of its uselessness, when some tradition is actually give a specific kris a bath once a year.
The actual situation shows that kris is rare enough from a long time ago, while the tombak (pike) is standard weapon for armies.
